vices for fluid actuated motors, and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out in the claims.

The invention is illustrated in the accompanying drawings as follows:

Figure 1 shows a central vertical sectlon through the governor on the line11 in Figs. 2 and 3. Fig. 2 is asection on the line 22 in Fig. 1. Fig. 3 is a section on the line 33 in Fig. 1.

1 marks the controlling valve body, 2 the diaphragm in the body, 3 the valveico-acting with the diaphragm, the valve being arranged to move axially through walls of the diaphragm, 4: the cover for the valve body, 5 a gland on the cover, and 6 a valve stem secured to the valve. The governor frame 7 extends upwardly from the cover 1 and has the bearing sleeve 8- across its top, the axis of the sleeve being horizontal- Bearings 9 and 10 preferably formed of Babbitt metal are arranged on the endsof this sleeve and a governor spindle 11 is journaled in these bearings. The drive pulley 12 is fixed on the spindle by a set screw 13.

The carrier 14 for the governor is carried by the spindle 11 at the opposite end of the spindle from the pulley 12. It has a key groove 15 in which the roller 16 operates to lock the carrier against rotation relatively to the spindle.- The roller 16 .is

mounted on the spindle 11 by means of the pin 17. i

The weights 18 (see Fig. 2) have th shanks 19 which extend between the raised portion 20 on the inner face of the carrier 1% and the ears 21 extending inwardly from the surrounding flange of the carrier. The pins 22 extend through perforations 22 of the ears and the shanks 19- of the weights and into the carrier forming pivotal mountings for the weights 18. The cars 21 are each provided with two perforations, one of which in each ear I have marked 22". Pins 23 are arranged in the perforations 22? and means, of the pins 33.

. the springs 24 extend from these 23 CONRADER,

into slots 25 in theends of the weights where they are secured by the pins 26, the springs 24 forming a part of the centripetal element of the governor. The perforations 22 and 22 are similar in relation to theother parts of the governor so that the weights may be reversed if desired, the pins 22 being arranged in the perforation 22 and the pins 23 in the perforation 22 for this purpose.

Pins 27 are arranged in the perforations 28 in the weights. These pins are parallel to the spindle 11. They are seated against a bearing piece 29 which is arranged in a socket in the side of the weight. The outer face of this bearing piece is rounded and forms a bearing between the "weight and the face of the carrier 14 so as to take a part of the thrust on the pin 27 as the weights are moved outwardly. The outer ends of the pins are crotched at 30, and the links 31 are secured in the crotched ends by means of thepins 32; Theopposite ends of the links extend between the cars 34.- on a sleeve 35 and are pivotally secured thereto by y y y Thesleeve is slotted at '36 to permit the links to seat themselvesin the sleeve when the weights are intheir .closed position. The spindle has the reduced end 37 for receivingthe sleeve 35, andlthis. forms the shoulder 38 which looks the sleeve agamst axial movement in i one direction, and the washer 39 is arranged on the end of the spindle for locking the sleeve against axial movement in the opposite direction. A screw 40 is screwed into the endiof the spindle, and holds the washer inplace. i

i It will be readily observed that the pins 27 being free to rotate in the weights, and the sleeve 35 being free to rotate on the spindle asthe weights move outwardly, the swinging movement of the weights on the pins 22 ,is compensated for by the rotation of the pins 27 and'the rotation of the sleeve 35 so that there is no binding of the parts; On the other hand, it will be observed that as the weights move outwardly, the sleeve 35 being locked against axial movement, the pins 33Tare fixed against axial movement so that with the outward swinging on the weights, the outer ends of the links must swing with the pins 33 as a center and base,

and the result 1s that as the weights move moved axially,- and the governoris actuated, through this movement of the carrier. This arrangement of weights and carrier permits of the complete housing of the carrier, there being preferably yaplate 14 on the outer face which completely incloses the links and weights; I

In order to lubricate the parts withinthe governor, the part 37' is provided with a perforation 37 and the screw 10 has the central perforation communicating with the perforation 37 -A lateral perforation 37' leadsthrough the end 37 so that oil may pass from the opening 87 to the hearing between the sleeve and extension 37; Laterals 37 are arranged through the sleeve opposite the openings 31 in the ends of the link so that oil moving through the laterals 37 passes into the openings 31 and-thus lubricates the links. Some oil passes the links, and thus is carried into the carrier,

parts follows. There is also a lateral 11 leading from the opening 87 to the bearing between the-carrier and the spindle.

A lever 41 is pivoted on the pin 4:2 between the ears 43, the ears 13 extending from the frame 7. This lever has the throated end forming the arms 44:. Rolls 4-5, are arranged 011 pins 16 at opposite sides of" this arm. The pins 16 have the perforations 47 with lateral'ends 4-8 for lubricating the rolls. The rolls engage a washer 19 on the-face of the'carrier.

:A bar 50, is pivoted on apin {51 between the ends of the arms 4-1. A spring base 52 is arranged in the center of the bar 50. A spring'58 is arranged between the base 52 and the base 54,.the base 54 being on the end of a screw 55. The screw 55 is arranged in a lug 56, and is provided with a handle 57 bymeans of which the screw may be actuated toiadjust the spring 53, and'the screw is lockedlin adjustment by the nut 58.

f-The spindle 11 has the circumferential grooves 59 which are filled by the annular shoulders 60inthe bearing 9 so as to'prevent the endwise movement ofthe spindle under thepressure ofthe spring 53.

The lever'tl extends through an opening 61' in the frame 7, and is provided with a throated end 62, the arms of which are rounded, and extend each side of the spool 63, the roundedpart of the arms engaging the shoulders of .the spool. The spool is internally screw threaded, and screwed on to the end of the. stem 6. 'The stem can be adjusted in the spool to control the initial position of the valve, and locked in adjustment by the j am nuts at its ends.

I have arranged an automatic stop device in"'the"drawings, although this forms no part ofthe invention. A finger 107 is arranged orrthe spool 63 in the path of a finger 108, the finger 108 is carried on the of a strap 118, and a clamping screw 118".

A rider pulley 119 rests normally on the driving belt 120. A spring 121 extends from a perforation 122 in the lever 113 to a perforation 123 in the frame 7, and is of suflicient strength to immediately close the valve against the spring 52 when released. When the belt breaks, the pulley 119 drops carrying the flange 116 from under the roller 115., thus releasing the lever 113 and eflecting'the closing of the valve.
